This is your complete guide to understanding SAP CTM and configuring it to meet today’s inventory and planning methods. Throughout the book you’ll find detailed coverage of the functions and their usage. You’ll learn about customization of inventory and production planning with SAP CTM, including a clear explanation of the SAP CTM engine algorithm and several modeling optimization techniques. And you’ll learn how to analyze the CTM planning results using a variety of tools and techniques.

First, benefit from a detailed overview of SCM/APO planning and all of its key components, including DP (Demand Planning), SNP (Supply Network Planning), PP/DS (Production Planning and Detailed Scheduling), and GTP modules.Then, you'll uncover the ins and outs of Demand Processing as you explore the basic and advanced methods that can be used to influence demand prioritization and aggregation. Next, the author shows you how CTM planning categorizes all receipts and available stocks before each planning run and helps you easily understand the key configurations required to implement supply categorization using supply limits based on quantity or ATP categories. With exclusive insights into the planning engine algorithm used by the CTM engine, including an introduction to constraints programming and the different problems it can solve, you will be able to hit the ground running with this powerful tool. Last but not least, readers learn all the essential details for finding and analyzing planning results in case of any unfulfilled or late demands.
